Guys, I recently heard that if I used synthetic gear oil, I won't need the friction modifier for trac-locks. Is this true? Also, what weight oil is preferred- 90 wt?
Thanks,
Daniel

Daniel from what Alex has said "85w-140w"
Don't add any friction modifier if you want to use it more for racing. It will grab better without it.------------------

Thanks! It's going in my daily driver, so I'll probably add the modifier. Any ideas about the synthetic lube not needing the modifier?

I'd be inclined to just start out with the synthetic only, and add the modifier if chattering was a problem. ------------------

My book says 5 pints of SAE 90 for temperatures above 25*F or SAE 80 below 25*F It also specifies 1 ounce of C1AA-19B546-A limited slip additive per pint of gear lube. {In other words 5 ounces} ------------------
